Global Warming

पर्यावरणं संरक्षणं सञ्चालयम् । (Protecting the environment is our responsibility.)

The greenhouse effect involves the transfer of infrared radiation energy. Solar radiation passes through the Earth's atmosphere and warms the surface. The Earth then emits infrared radiation back towards the atmosphere, where greenhouse gases trap some of this energy, leading to a warming effect.

Humans have put carbon dioxide in the air mainly through burning fossil fuels for energy, such as coal, oil, and natural gas. Deforestation and other land use changes also release carbon dioxide into the atmosphere. Additionally, industrial processes and transportation also contribute to carbon dioxide emissions.

This is so because CO2 is a green house gas which does not allow the harmful UV rays of the sun trapped by the Earth to go back , which increases the temperature of the Earth.

So if carbon dioxide will increase , surely the temperature would also increase.

Some scientists, University of Chicago oceanographer David Archer and Ken Caldeira of the Carnegie Institution for Science in Stanford, California, are showing studies that say CO2 levels will remain in the atmosphere for a few centuries, "plus 25 percent that lasts essentially forever".

"The climatic impacts of releasing fossil fuel CO2 to the atmosphere will last longer than Stonehenge," Archer writes. "Longer than time capsules, longer than nuclear waste, far longer than the age of human civilization so far."

No, carbon dioxide levels in the atmosphere increaseduring autumn and winter. When spring begins in the northern hemisphere (where most of the world's vegetation is) all the growing plants and trees start taking carbon dioxide out of the atmosphere. They continue during their growing spell during spring and summer. As the weather gets colder they stop growing. Then the carbon dioxide builds up in the atmosphere.

The Maldives are facing the threat of rising sea levels, which puts the low-lying islands in danger of being flooded and uninhabitable in the future. The government is implementing measures such as building artificial islands and investing in renewable energy to mitigate the effects of climate change. However, the long-term future of the Maldives depends on global efforts to reduce greenhouse gas emissions and combat climate change.

Chemical and biological weathering are different because:

a) biological weathering - this means that if a seed of a plant gets coincidentally deposited in a crack in a rock, if it is humid enough, the see will grow. it's roots will spread out and eventually break the rock.

b) chemical weathering - this means that chemicals in rain/acid rain weathers away the rock.

The enhanced greenhouse effect is happening because we are adding additional carbon dioxide and methane to the atmosphere. These greenhouse gases trap in heat from the sun making the earth warmer.

The expansion of international NGOs refers to the growth in number and influence of non-governmental organizations operating across borders. These organizations play a significant role in global affairs by addressing humanitarian crises, promoting human rights, and advocating for social and environmental issues. They provide a platform for global advocacy, collaboration, and accountability, influencing policies and shaping discourse on important global issues.

Iron oxide is a reddish-brown compound commonly referred to as rust. Polar ice caps are regions of a planet's surface where ice permanently accumulates. The presence of iron oxide in polar ice caps can give them a reddish color, like the red snow in Antarctica caused by iron-oxidizing bacteria.

• Burning fossil fuels (coal, oil and natural gas) in travel, industry and to generate electricity adds extra carbon dioxide into the air.
• Agriculture practices, especially cattle raising, adds increased methane into the air.
• Deforestation means there are far fewer trees to remove carbon dioxide from the air.
• These extra greenhouse gases are too much for the carbon cycle to remove and the gases are warming up and so the global temperature increases.

The main effect and issue of carbon dioxide on the environment is the fact it is a greenhouse gas. A greenhouse gas is a gas that creates a barrier in the atmosphere and does not allow excess heat to escape the atmosphere into space (like in a greenhouse ). This means that there is a build up of temperature, which will eventually lead to a rise of 1-2 degrees Celsius at the equator (bearing in mind that a 1 degree change at the equator = 12 degree change at the poles.)

The very fact that there are ice caps in and around the Arctic means we are in an ice age.

It started 2.6 million years ago and we are now in a warm period we call an interglacial.

If the ice caps melted very quickly it could allow a lot of fresh water into the northern oceans so altering the flow of warmer water from the south. This could mean that those countries in the north will not receive the warming waters we need to stave off another glaciation.

If the ice caps melted slowly however, it could mean we would leave the ice age for a long time. The downside to that means that hot countries could become hotter and drier.

The main way in which climate change is affecting koalas is that Australia is becoming prone to more frequent and intense bushfires which, of course, kill koalas. Eucalyptus bushland will always regenerate after a bushfire - that is the way Australian native plants are designed - but the impact on the koala population can be quite devastating. Koalas simply have nowhere to run and hide during a bushfire.

Another way in which climate change can affect koalas is that, with increasing droughts that extend over a wider range and continue for longer, this does impact on healthy gum trees of the type favoured by koalas. As a consequence, koalas are more likely to wander beyond their home trees, which uts them at risk of being hit by cars or attacked by dogs.

People can affect each other through their words, actions, and presence. Positive interactions can lead to feelings of happiness, connection, and support, while negative interactions can cause stress, conflict, and hurt. Ultimately, human relationships play a significant role in shaping our emotions, behaviors, and overall well-being.

Biofuel production does not increase carbon dioxide levels. Biofuel comes from recently grown vegetation of many kinds. When the vegetation grew earlier in the season it took carbon dioxide out of the air. When the biofuel is extracted and burnt that same carbon dioxide is released into the air again. There is no increase of carbon dioxide. Biofuel is carbon neutral.

This is the problem with fossil fuels, who took carbon from the air many millions of years ago. Suddenly releasing this now is adding to the greenhouse gas levels and causing global warming.

They don't. Climate change occurs on the Earth. Sun spots and solar flares occur on the Sun. The Sun heating up could cause a climate change on the Earth, but sunspots and solar flares don't really have much to do with that.

No, animals will have their habitats destroyed and plant and tree species will disappear. Actually, everything living on the planet are victims of global warming, but humans are the cause of it.

yes of course solar energy is a GREAT source of energy

Most of us have some big and some small things all around us, and things that they can do to better the cost efficiency of home. Whether you just want to drop a few dollars off of your gas bill or you are looking for a better way to fuel your home altogether, doing just a few things can make a tremendous amount of difference in your home.

Yes, global warming is happening everywhere and its effects will certainly be felt in Louisville, Kentucky. Climate change means just that.

We should all be concerned about global warming because of the harm it can do to our planet, our society and our economy. Global warming threatens climate change that will result in widespread species extinction, droughts in some areas but more frequent severe floods in others, sea level rises that, along with higher storm surges, could result in entire populations having to abandon their homes, and more intense storm activity that will cause economic hardship.
